Title: Improvements in or relating to knitted fabrics and to methods for producing such fabrics
IPC: D04B9/54
Filed: 1941-04-28
Abstract: 548,951. Knitting. HEMPHILL CO. April 28, 1941, No. 5501. Convention date, April 29, 1940. Drawings to Specification. [Class 74 (ii)] A method of knitting a non-curling edge for e.g. a plain hosiery top consists in drawing an elastic yarn so that a plurality of loops thereof will be held at spaced wales or groups of wales and then drawing a non-elastic yarn and casting- off the loops of elastic. Thereafter several courses of non-elastic yarn are drawn while the elastic yarn is laid in at spaced wales and the non-elastic yarn is tucked at intermediate wales. The elastic yarn is drawn over sinker ribs and dropped from the ribs to rest in the sinker throats prior to arrival at the feeding station for non- elastic yarn. The sinkers are selected so that spaced sinkers or. spaced groups of sinkers have elastic yarn drawn over their ribs while the intermediate sinkers are in withdrawn position so that the yarn is drawn forwardly of their nibs. Specification 473,924 is referred to

Title: Process and apparatus for producing acetylene and lime hydrate
IPC: C10H13/00
Filed: 1937-02-27
Abstract: <PICT:0483601/IV/1> Acetylene and substantially dry calcium hydrate are made by a continuous process wherein calcium carbide is treated with an amount of water sufficiently large to react with the carbide but sufficiently small to produce a reaction temperature somewhat above the boiling point of water but below the decomposition temperature of acetylene, (i.e., below about 400 DEG  C.), the reaction being effected in a chamber to which fresh carbide is continuously fed and through which the unreacted carbide and the calcium hydrate produced are positively conveyed, with agitation. As shown, carbide is fed from a hopper 15 by a screw 19 to a horizontal chamber 36 through which it is conveyed by paddles 35 and to which water is supplied through a pipe 41 and nozzles 47. The chamber 36 communicates with a second similar chamber 37, from which calcium hydrate is discharged to a hopper 33.  The generated acetylene passes by way of pipe 50 through a dust-separator, 51 and cooler 56 to a gas holder, from which by way of a pipe 66 and seals 68, acetylene may return to the carbide hoppers and to the chamber 36 should a reduction in pressure occur.  A modified apparatus is described, Figs. 3 and 4 (not shown), in which (a) means are provided for passing a cooling fluid through the shaft carrying the paddles 35, 35a, (b) the water is introduced tangentially into the chambers 36, 37 and (c) a number of pipes for the passage of the acetylene are provided along the top of each chamber.  In a further modification, Fig. 5 (not shown), the water is introduced into the chambers 36, 37 from below.

Abstract: 963,898. Milling. KEARNEY & TRECKER CORPORATION. Feb. 21, 1961 [Oct. 14, 1960], No. 6299/61. Heading B3K. [Also in Division F2] In a screw-and-nut mechanism for moving a work-supporting table 18 of a milling machine, a lead screw 21 is journalled in the machine bed 10 and carries a pair of nuts 28, 28A located on opposite sides of an abutment 25 on the table 18, the nuts 28, 28A are interconnected for simultaneous rotation in opposite directions relative to the screw to effect their simultaneous axial movement toward and away from the abutment 25, and one-way clutches 30, 30A are arranged to release when the nuts are moved away from the abutment 25 in order to relieve the frictional engagement of the nuts with the abutment. The nuts 28, 28A are integral with gears 31, 31A which are interconnected through gears 61, 62, and a spring- pressed rack 72 meshes gear 61. The rack 72 is located in a bore 73 and has an adjustable end stud 77. When the screw 21 is driven in a counter-clockwise direction, as viewed from the left in Fig. 4, to effect rightward movement of the table, the conventional cutting force F urges the table 18 to the left, thereby causing the nut 28A to rotate with the screw 21 which, in turn, causes rotation of nut 28 to move it axially away from the abutment 25, thereby relieving tension in the portion of the screw 21 between the nuts 28, 28A. The rotation of the nuts 28, 28A is limited by the engagement of the rack stud 77 with the end of the bore 73, whereby the nut 28A is held against rotation in order to effect axial movement of the table 18. During a climb-cutting operation, the nuts 28, 28A tighten against the abutment 25.

Abstract: 622,175. Electric coffee percolators. BRITISH THOMSON-HOUSTON CO., Ltd. March 7, 1947, No. 6473. Convention date, March 9, 1946. [Class 39 (iii)] [Also in Group XXXVII] In a vacuum-type coffee maker of the type comprising a water-heating bowl connected to an infusion bowl by a liquid transfer tube, a control magnet is held in one position by an armature which is movable to release the magnet to permit it to move to a second position in which it is held by a further armature. The magnet 18, which may be of sintered alnico, has north and south poles on both its upper and lower ends and is mounted to move vertically within a cylindrical casing 19. A cover plate 27 for the latter is pressed by a spring 29 upwardly into contact with the bottom of the lower bowl 1 of the percolator. In its lower position, the magnet is attracted by a fixed armature 23 and presses upon a plunger 30 to retain a switch 31 in the open position. On depression of a push-button 36, the magnet 18 is lifted by means of a lever 32 and the plunger 30 to its upper position, in which it is retained by the attraction of a nickel armature 40, in consequence, the switch 31 closes to energize a heater winding 10. Boiling water passes by way of a transfer tube 4 from the lower bowl 1 to an upper bowl containing the coffee grounds, and eventually attains sufficient velocity to act on a disc 43 to raise the armature 40 into the dotted position, allowing the magnet 18 to fall to its lower position and open the switch 31. Preferably, as the temperature falls, a thermostatic switch closes to connect the heater winding 10 in series with an auxiliary heater winding 15 to provide a low heat to keep the coffee brew warm. There may be an indicator light in series with the heater winding 15. Specification 550,632 is referred to.
